Beautiful FD's, Arne. I saw your photos from October 23rd, fingers crossed so that the weather will allow you to follow the movement of the new AR.

You caught that low Norway sun quite well! Looks good! I love the blackened out disc with the detached proms in the SW!!

Re: Sun FD in H-Alpha and CaK 22nd of October 2021
Thank you very much, Ivan and James.
Ivan:
Looks like no Sun today or tomorrow :-( Maybe on Tuesday perhaps.
James:
The low solar altitude is really starting to make things challenging. Maximum solar altitude is only 19 degrees at the moment.
Best regards,
Arne

That's a nice schematic Arne, where did you get that from? I wouldn't mind doing one for my location. I'm at 53N and I think the altitude gets to 12-15 degrees or so (not sure).
